My invention relates to improvements in window sash. An object of the invention is to provide a structure in which loss of heat is reduced to a minimum. Window frames or sash made of metal as generally constructed, permit an escape of large amounts of heat conducted therethrough. Owing to such heat conductivity, double glazing for use with metal sash has been rendered comparatively inefiicient as a means of preventing heat losses. 7

An object of the present invention is to reduce such heat losses to a minimum by the provision of a window sash particularly adapted for use with hollow window panes or blocks, as well as for either single or double glazing, so constructed as to permit the transmission and escape of comparatively little heat.

A further object of the invention is to provide a construction suitable for use in rooms where exposed metal frames would be subjected to the destructive action of corrosive fumes or gases. To this end the invention provides a metal framework or sash of such construction that no portion of the framework between the adjoining panes of glass projects into an exposed position, and in which the framework is adequately protected by sealin material which is inert or resistant to the action of such destructive gases.

A further object of the invention is to provide a window comprising a metal sash or framework, with insulating material overlying and covering the spacing bars between the edges of adjoining window panes.

v Other objects of the invention will appear hereinafter.

Referring to the accompanying drawings:

8 Claims. (01. 18976) Fig. 8 is a sectional elevation, with parts broken, away, of the structure shown in Fig. 7.

Referring to Figs. 1, 2, and 3, the sash as lustrated, comprises a rectangular frame III, which may be made of steel or other metal, and inner cross bars ll integral therewith, thereby; forming a panel. framework. Each of the sides and ends of the frame I0 is in the form of a longi-g tudinal bar l2 or body portion havinga vertical front face, and anintegralledge l3 projecting horizontally from the opposite side'thereof. The uper face of the ledge I3 is formed with an intermediate longitudinal rib M which together with,

the part I2, provides a recess l5 to receivethe interior sealedspace or chamber 19, Theblock is formed with front and rear marginal ribs" 20 and 2| respectively,spaced apart to provide a recess 22. When the glass is placed in the frame, the rib 20 enters the recess 1 51: A lining or gasket" 23 of asphalt or the like, is: preferably attached, or applied to the frame'in position to provide a;

backing for, the glass and particularly for the" flange portion 20. The bars I l are also provided;

witha layer or facingllofsuch material.

The glass is secured in position in the frame by clamping devices comprising metal clips 25- positioned at intervals along the bars ll. 'Thes'e' clips are preferably in the form of flat strips each? having an end portion bent at right angles andj inset into and flush with theface ofth'e bar Ill The clips are spot-welded to the bars H and, as

' shown, are, arranged in pairswith the clips on g Y Fig. 6 is a. sectional elevation showing partic opposite sides of the ribs l1 and projecting out wardly'beyond said ribs. When a pane of glass It has been placed on the frame, thefree ends" of the clips are bent to embra'ceth rib20 of the glass and thereby securely hold the latter in place.

When'panes of glass are placed in the frame," the adjacent edges of the glass 'provide longi'-:

tudinal channels 26 which may be substantially rectangular in cross section. These are prefer ably packedwith thermal insulating material 21,

such as glass wool, rock wool, or other fibrous insulating material which may be introduced through the opening 28 provided between the ribs 2|. The space 28 is then filled with caulking material 29 which may be any approved commercial caulking which is permanently sufiiciently soft and elastic to maintain a tight seal. Caulking material 39 is also introduced between the frame I!) and the margins of the glass extending therealong as indicated in Fig. 1. This caulking mate rial extends inwardly and adjoins the liningv 23. It will be seen that with this construction, the glass is separted from the metal frame by heat insulating and cushioning material. be noted that the spacin ribs I! are well insulated so that practically no heat can be transmitted through thespace betweentheadj cent.

edges of the glass along said ribs;. 1

Figs. 4, 5, and 6 illustrate a construction comprising a modified form of clamping device or fastening means for securing the glass in the frame. In this instance; screws 3| are provided atintervalsalong thebars H and are threaded i o Openings flinthe bars, which openings may extend through the ribs. ll. The glass is held in position by. washers 33 clamped thereagainst. by. thescrews...
